Image Processing

Original Image – Riri

This is a python work. Works given below applied to original image.

  • Image is devided into four quadrants:
    • Q1 is the original image,
    • Brightness increase is applied to Q2,
    • Contrast increase is applied to Q3,
    • Histogram equalization is applied to Q4
    • Then, Q1 and modified Q2, Q3, Q4 are merged into a single image.
  • Histograms of each quadrant are shown.
  • 5×5 non-linear median filter / kernel is applied to an image.
  • Image is transformed to Fourier Transform, high frequency components are filtered out.
